| Outline of Final Research Achievements |
The iso-cis-1,4- and iso-trans-1,4-specific polymerization of (E)-1,3-pentadiene have been achieved by using cationic rare-earth metal catalysts. The obtained polymers were isotactic-cis-1,4-polyPD (ICPPD; mmmm > 99%, cis-1,4 > 99%) and isotactic-trans-1,4-polyPD (ITPPD; trans-1,4 = 94%). Hydrogenation of ICPPD and ITPPD with p-toluenesulfonylhydrazide afforded perfect poly(ethylene-alt-propylene) rubbers (EPM) and poly(ethylene-propylene-diene) rubbers (EPDM).
